Abstract

This is a software upgrade proposal for Paloma to v1.15.7for Paloma’s TESTNEST and MAINNEST tumbler networks. This release includes upgrades to Paloma that include fixes to the Paloma Skyway bridge ERC-20 token attestation on the deployment of Compass-EVM

Motivation

The motivations for this Paloma upgrade include the following:

  1. Fix compass attestation with ERC20 tokens

Specification Overview

The specification for this release includes the following features:

  1. Fix compass attestation with ERC20 tokens.

Technical Specification

When some chains have deployed ERC20 tokens, compass upgrades would be stuck on chains that do not have tokens. Now, we only query deployed tokens for the specific chain currently being iterated. NOTE: After deploying this change, we have to manually remove any stuck compass upgrade. It should redeploy automatically afterward.

Prior to upgrade

  1. An upgrade proposal that must be submitted by anyone running a node on the network. This proposal should have the correct block height.
  2. Please use the following spreadsheet to calculate the approximate Block Height. https://docs.google.com/spreadsheets/d/1eoXoDWWYHIOYbdPiv8B6vfwDUUkelZgeifnX4foa7yw/edit#gid=0
  3. This upgrade proposal requires 10 GRAIN or 10000000ugrain for deposit for voting.
  4. IMPORTANT: The upgrade height is the block height where the chain halts and requires the upgrade. Allow at least one (1) day AFTER voting end time and upgrade-height for 2/3 of the network to have downloaded the new binary and prepped for the switch over to avoid/minimize downtime of the Paloma chain.
  5. The Target block height for chain halt for this proposal is tentative 21886955 or approximately 08/12/2024, 14:25 UTC See (Block height: 21886955)

How to check if 2/3 of the network is online after the vote is complete

To see which validators are online with the new binary, use GitHub - blockpane/pvtop: top-like tui for watching validator pre-votes on Tendermint chains

Rationale

We are upgrading Paloma to achieve the following objectives:

  1. Fix compass attestation with ERC20 tokens.
